Hi Steve, went to the boat this weekend. Removed the condensing unit from the boat, and yes the valve is a 1/2 inch connection (NFL) but the copper line is 3/8". That was the confussion. The compressor is an AK8515E. Seems to be the original. The capacitor strap is painted blue so there is no model #. I already ordered the new valve and I am in the process of fabricating the bases at a shop here. I will test the compressor for suction pressure and RLA & LRA. I need to work also in the 2nd unit which is working ok now but is all rusted at the base and at the reciever. I also need 2 of the rubber-foot of the base. The capillary tube is a pressure sensor to cut-off the compressor @ high pressure? Yes there is a cap tube for that.

The idea of getting seawater all the way up at the Flybridge does not look too easy. There is a replacement compressor AK8515EXA, This compressor is OK to use…I noticed a new 16 with the XA extension to the model # the other day… but I've heard that there are some difference inside the marine compressor such as valves and other things. I thought that the model # was enough to garantee same specs. Anyway I hope the compressor is still working. I will try with a boost capacitor and maybe replace the starting capacitor. What about the voltage relay??? Does that need to be replaced at all. If this is the relay that activates then turn off the starting capacitor, could that be the reason for turning but not starting at all.

Also found that the breakers were 20 amps. I think I measured the amps in the past and found it was 16 amps for the complete unit, including fan and water pump. Anyway thanks for the help I will keep you posted in the future.
